These tables incorporate only the commonest host crystals; numerous Other folks exist, which can be a lot less frequently employed.

激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

Laser crystals are optical crystals �?generally single crystals (monocrystalline optical materials) �?that are made use of as obtain media for stable-condition lasers. Generally, They are really doped with either trivalent exceptional earth ions or transition metal ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping concentration of the gain medium are most useful count on quite a few things. The readily available pump supply (kind of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the fabric alone also has some affect. As an example, titanium–sapphire lasers must be pumped with large intensities, for which the form of the transversely cooled rod, operated with somewhat modest pump and laser beam diameter, is more ideal than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

A number of laser crystal materials happen to be demonstrated exactly where some saturable absorber product is included for passive Q switching of the more info laser.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

For quasi-3-amount laser gain media or perhaps a few-degree obtain media, 1 typically must limit the size to a worth that's way too short for productive pump absorption, as reabsorption consequences would if not spoil the performance. For side pumping, further issues come into Perform; Other than efficient pump absorption, it's important to acquire an acceptable spatial form with the get profile.

Distinctive crystalline resources are very diverse about their hardness and also other Qualities, which ascertain with which techniques And exactly how effortlessly they can be Minimize and polished with high quality.

For numerous factors, composite crystals are getting to be common. These have a spatially different chemical composition and may be created with Exclusive shapes.

There is certainly a wide array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some essential groups of crystals are:

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
